  FIG. 2 is a perspective view from the oblique player side of the lower half of the percussion instrument apparatus showing a state in which the foot pedal apparatus of the present embodiment is mounted. In the frame portion 13, a beater support portion 35 is fixed below the bass drum board 12, and the beater body 30 is attached to the beater support portion 35 via two shaft support pieces 36. The beater body 30 is configured such that a beater 33 that strikes the bass drum board 12 is attached to the tip of a beater rod 32 extending from the rotation fulcrum 31. Further, in order to perform, a foot pedal device 40 is disposed on the floor from the lower side in the center of the main board 10 to the player side.

  FIG. 3A is a plan view of the foot pedal device 40. FIG. 3B is a bottom view of a part 43a of the frame portion 43 described later, and FIG. 3C is a cross-sectional view taken along line AA of FIG.

  The foot pedal device 40 includes a holding frame body 41, a pedal portion 50, and a locking pin 55. The holding frame body 41 and the pedal portion 50 are integrally formed of, for example, metal or resin. That is, the holding frame body 41 has a base portion 42 and a frame portion 43, and an opening 45 is formed in the frame portion 43. The opening 45 is substantially the same as the shape of the outer edge 53 of the pedal portion 50 in a plan view, and is formed in a shape just like the pedal portion 50 is cut out from a flat plate. And the base end part 51 of the pedal part 50 is connected in the edge | side by the side of the base 42 in the opening part 45, and the front-end | tip part 52 of the pedal part 50 is made into the upper and lower sides by setting this connection part (hinge part) as the rotation center 47. It can swing freely in the direction.

  In the free state in which the pedal portion 50 is not depressed, the distal end portion 52 is lifted from the holding frame body 41 as shown in FIG. When the holding frame body 41 and the pedal portion 50 are made of metal, the holding frame body 41 and the pedal portion 50 are manufactured, for example, by cutting and raising the pedal portion 50 from a flat plate to have a predetermined angle by plastic working. In the case of using resin, it can be manufactured by integral molding using a mold.

  FIG. 3A shows a state where the pedal portion 50 is stepped on or a state where the pedal portion 50 is rotated until it is parallel to the holding frame body 41 for storage. The holding frame body 41 and the pedal portion 50 are configured to have the same thickness, and the pedal portion 50 is completely fitted into the opening 45 of the holding frame body 41 and held in a state parallel to the holding frame body 41. The frame 41 is completely accommodated in the holding frame 41 in the thickness direction of the frame 41. In addition, since it is sufficient that the pedal portion 50 can be completely accommodated in the holding frame body 41, the thickness of the pedal portion 50 is equal to or less than that of the holding frame body 41, and the bottom surface and the upper surface of the pedal portion 50 are the holding frame body 41. What is necessary is just to comprise so that it may become flush | planar with respect to the bottom face and upper surface of each, or may not protrude.

  A fitting hole 46 penetrating in the vertical direction is formed in the distal end portion 44 of the holding frame body 41. In addition, two extended pieces 54 are formed to extend in the distal direction at the distal end portion 52 of the pedal portion 50, and the above-described locking pin 55 is installed between the extended pieces 54. When performing, the rotation fulcrum 31 of the beater body 30 and the locking pin 55 are connected by a belt 37 (described later) that transmits the stepping operation of the pedal unit 50 to the rotation fulcrum 31.

  Although not shown in the drawings, a separate storage case is provided for storing the pedal unit 50 in a state in which the pedal unit 50 remains parallel to the holding frame body 41. That is, the storage case has a pocket-shaped recess having a width and a height that allows the holding frame 41 to be fitted, and the pedal portion 50 remains parallel to the holding frame 41 in the recess. Maintained in a posture. Instead of such a separate storage case, a lock mechanism for maintaining a parallel state may be provided in either the holding frame body 41 or the pedal portion 50. For example, the holding frame body 41 is provided with a slidable pin, the pedal portion 50 is provided with a hole into which the pin can be fitted, and the pin is fitted into the hole so that the parallel state is maintained. Good.

  In this case, for example, the pin is incorporated in the connection portions 44 a and 44 b (see FIG. 3A) between the distal end portion 44 of the holding frame body 41 and the frame portion 43. And the hole which fits into the said pin is provided in the two extended pieces 54. FIG.

As shown in FIGS. 3B and 3C, the holding frame body 41 is flat in appearance, but the inside of the frame portion 43 of the holding frame body 41 includes a plurality of vertical ribs. And a recess formed between the ribs. The entire frame portion 43 is configured in this way. Thus, the holding frame body 41 only needs to have a flat outermost shape in the vertical cross section, and may have a recess on the front surface or the back surface, or may not have at all. The pedal unit 50 is similar to this.

FIG. 4A is a perspective view of the front end portion 52 of the pedal portion 50 and the lower end portion of the belt 37. Horizontally extending pieces 37a and 37b are formed at the lower end portion of the belt 37, and a screw 38 is provided on the extending piece 37a downward (in the direction of the extending piece 37b).

  In order to connect the front end portion 52 of the pedal portion 50 and the belt 37, first, the locking pin 55 of the pedal portion 50 is inserted between the extending pieces 37 a and 37 b, and the screw 38 is set to be based on the locking pin 55. It is located on the end 51 side. Then, the screw 38 is tightened until the lower end of the screw 38 reaches below the locking pin 55. As a result, the locking pin 55 does not come off from the extended pieces 37a and 37b, and the connection is completed. When removing, the screw 38 may be loosened.

  FIG. 4B is a right side view of the vicinity of the beater support portion 35. As shown in FIG. 2 and FIG. 4B, two shaft support pieces 36 (only the right one is shown) are extended from the beater support portion 35 to the player side. A rotation fulcrum portion 31 is pivotally supported on a rotation shaft 34 (see FIG. 4B) that is installed between the two shaft support pieces 36. Thus, the beater 33 is rotatable about the rotation shaft 34 via the rotation fulcrum 31 and the beater rod 32, and the bass drum board 12 is hit by the beater 33.

  Further, in the semicircular cylindrical portion 31a having a semicircular shape in a side view on the rear side of the rotation fulcrum portion 31, a portion facing the beater support portion 35 with the beater rod 32 facing upward in the vertical direction is a belt attachment portion 31aa. It has become. The upper end of the belt 37 is attached to the belt attaching portion 31aa. In addition, a locking portion 31ab is formed to protrude from a portion of the semi-cylindrical portion 31a above the belt mounting portion 31aa.

  The beater support portion 35 is provided with a rotation lock mechanism 26. The rotation lock mechanism 26 includes a block 27 fixed to the beater support portion 35, an in / out pin 29 that can be freely moved in and out of the block 27, and an operation unit 28 that operates the in / out movement of the in / out pin 29. . When performing, the in / out pin 29 is stored in the block 27. When the beater rod 32 is directed upward in the vertical direction when the performance is not being performed or the like, the tip of the bump pin 29 is positioned immediately above the locking portion 31ab.

  Here, in a state where the front end portion 52 of the pedal portion 50 and the belt 37 are not connected, the beater body 30 is in a freely rotatable state, and the beater 33 is fully rotated downward by its own weight. On the other hand, in a state where the distal end portion 52 of the pedal portion 50 and the lower end of the belt 37 are connected, the rotation fulcrum portion 31 receives a rotational moment in the striking direction from the distal end portion 52 of the pedal portion 50 via the belt 37. Therefore, as shown in FIG. 2, the beater 33 balances at a position obliquely upward as viewed from the rotation fulcrum portion 31 due to its own weight and the rotational moment. That is, it is separated from the bass drum board 12 by an appropriate amount and located at a position suitable for hitting.

  The operation of the appearance pin 29 is usually performed when the performance is not performed for a while. That is, it is performed when the beater body 30 is in the above-described free state, and in particular, with the beater rod 32 facing upward in the vertical direction with a hand or the like. When the retracting pin 29 is protruded above the locking portion 31ab, the beater 33 tries to rotate downward due to its own weight, but the retracting pin 29 and the locking portion 31ab come into contact with each other and the rotation is restricted. . Thereby, at the time of storage, the beater body 30 can be brought close to the main board 10 in a state of being nearly parallel to be compact in the thickness direction of the main board 10.

  FIG. 5 is a horizontal sectional view of the central portion of the main board 10 in the left-right direction. A plate 21 is fixed to the customer side of the main board 10. The plate 21 is provided at least in the lower part of the central portion in the left-right direction, but may be provided over the entire customer side surface of the main board 10. A recess 10 b is formed on the customer side of the main board 10. In the recess 10b, on the player side of the plate 21, a support member 22 is fixed with a plurality of screws 25, and a movable piece 23 (see also FIG. 2) is formed in a space formed by the support member 22 and the plate 21. The interior is movable in the vertical direction. Further, a knob 24 (see also FIG. 2) protrudes from the movable piece 23 through the support member 22 and the main board 10 toward the player side.

  The player can hold the knob 24 and move the movable piece 23 up and down. Note that, for example, an appropriate friction is generated between the movable piece 23 and the support member 22 so that the movable piece 23 can be stopped at a desired position.

  When performing, the foot pedal device 40 is placed on the floor so that the tip 44 of the holding frame 41 of the foot pedal device 40 is positioned below the movable piece 23. Then, the movable piece 23 is lowered and fitted into the fitting hole 46 (see FIG. 3A) of the holding frame 41 as shown in FIG. Accordingly, the position of the holding frame 41 of the foot pedal device 40 with respect to the main board 10 is fixed on the floor surface with a simple operation. Further, the locking pin 55 at the distal end portion 52 of the pedal portion 50 is sandwiched between the extending pieces 37a and 37b of the belt 37, and the screw 38 is tightened (see FIG. 4A). As a result, the performance becomes possible, and the beater 33 strikes the bass drum board 12 in response to the depressing operation of the pedal unit 50.

  According to the present embodiment, the pedal portion 50 has the same thickness as the holding frame body 41, and completely rotates into the opening 45 of the holding frame body 41 when rotated until it is parallel to the holding frame body 41. Since it is inserted and completely accommodated in the holding frame 41 in the thickness direction of the holding frame 41, the foot pedal device 40 can be folded and stored compactly when not in use.

  Further, the rotation fulcrum part 31 of the beater body 30 and the locking pin 55 of the distal end part 52 of the pedal part 50 can be connected / disconnected via the belt 37, and the movable piece 23 provided on the main board 10 can be connected. The holding frame body 41 of the foot pedal device 40 can also be connected / disconnected to / from the main board 10. Therefore, when not in use, the foot pedal device 40 can be separated from the beater body 30 and the main board 10 and stored compactly.

  Further, a rotation lock mechanism 26 is provided that maintains the state in which the beater body 30 is brought close to the main board 10 in parallel with the foot pedal device 40 separated from the beater body 30 and the main board 10. Thereby, when not in use, the main board 10 can be made compact in the thickness direction. For example, the main board 10 can be easily transported and stored with the beater body 30 attached.

  In the present embodiment, the holding frame body 41 and the pedal portion 50 are integrally formed, and the pedal portion 50 is swingable with respect to the holding frame body 41 around the rotation center 47. (See FIG. 3A.) The pedal unit 50 may be configured to be pivotally or swingably connected to a part of the inside of the opening 45 of the holding frame 41. It may be the body. For example, instead of the rotation center 47, both may be connected to each other with a connecting tool such as a hinge. In that case, similarly to a general foot pedal device, a member that holds the pedal portion 50 in a floating state and a spring that returns the depressed pedal portion 50 to the original floating state may be provided.

  In the present embodiment, the upper end of the belt 37 is always fixed to the belt attaching portion 31a (see FIG. 4B), but the present invention is not limited to this. For example, the belt attaching portion 31a may be configured to be detachable, and the belt 37 may be configured to be separable from both the beater body 30 and the foot pedal device 40 during storage.

  The belt 37 may be any member that transmits the pedaling force applied to the pedal unit 50 to the beater body 30, and the material and shape are not limited to those illustrated. For example, a metal chain or the like may be used.

  The lock mechanism 26 is not limited to the exemplified configuration as long as it can fix the beater body 30 with respect to the main board 10 when not in use.

  In addition, the main board 10 should just be a support body with which at least one drum board was fixed, and the kind of drum board and the shape of a support body are not ask | required.
